Subject: 2.6.27/2.6.28: irqbalance dies shortly after starting the daemon on
 x86 but not x86_64, why?

(same on both x86 and x86_64):
# cat /etc/default/irqbalance
#Configuration for the irqbalance daemon

#Should irqbalance be enabled?
ENABLED=1
#Balance the IRQs only once?
ONESHOT="0"

========
my x86 system:
========

# /etc/init.d/irqbalance start
Starting SMP IRQ Balancer: irqbalance.

# ps auxww | grep -i irqbalance
root      4570  0.0  0.0   2536   436 ?        Ss   07:07   0:00 /usr/sbin/irqbalance

# sleep 300; ps auxww | grep -i irqbalance
#

=========
On my x86_64 systems:
=========

$ ps auxww | grep -i irqbalance
root      2769  0.0  0.0   8828   492 ?        Ss   Dec27   0:06 /usr/sbin/irqbalance
$ ps auxww | grep -i irqbalance
root      2918  0.0  0.0   8828   520 ?        Ss   Dec22   0:18 /usr/sbin/irqbalance

Is there a bug on x86?

Justin.
